Hearing aid devices may also be measured for immunity to interference
noise from wireless phones and should have ratings similar to phones. Ask
your hearing healthcare professional for the rating of your hearing aid. Add
the rating of your hearing aid and your phone to determine probable
usability:
vAny combined rating equal to or greater than six offers excellent use.
vAny combined rating equal to five is considered normal use.
vAny combined rating equal to four is considered usable.
Thus, if you pair an M3 hearing aid with an M3 phone, you will have a
combined rating of six for “excellent use.”This is synonymous for T ratings.
SprintNextel further suggests you experiment with multiple phones (even
those not labeled M3/T3 or M4/T4) while in the store to find the one that
works best with your hearing aid device. Should you experience
interference or find the quality of service unsatisfactory after purchasing
your phone, promptly return it to the store within 30 days of purchase. With
the Sprint 30-day Risk-Free Guarantee, you may return the phone within 30
days of purchase for a full refund. More information about hearing aid
compatibility may be found at: www.fcc.gov,www.fda.gov,and
